水动力噪声计算方法综述

A review of the progress for computational methods of hydrodynamic noise

  • 摘要: 准确量化评估水动力噪声,对研制反潜水面舰船、安静型潜艇和隐身鱼雷等高性能航行体具有重要意义。由航行体型线变化、表面曲率不连续和各种扰动引起的三维非定常外流场是航行体水动力噪声的源场。分述航行体表面湍流边界层、空腔振荡、空化和粗糙度诱发水动力噪声的机理和研究进展。在分析水动力噪声数值预报难点的基础上,综述流体动力噪声计算方法研究进展。着重比较在航行体水动力噪声工程预报方面有较好前景的3种方法:声类比法、粘声分离法和声边界条件法。

     

    Abstract: It is of great importance to accurately evaluate submarine's hydrodynamic noise in order to develop anti-submarine surface warships, stealthy submarines and torpedoes as well as to optimize their hydrodynamic and acoustic performance.Specifically, the three dimensional unsteady flow field over the vehicle is usually caused by the changes of profile, discontinuity of surface curvature, and various perturbations.In this paper, the research progress of the vehicle's hydrodynamic noise induced by the turbulent boundary layer on the surface, cavity oscillations, cavitation, and roughness are introduced, respectively. By analyzing the difficulties in the numerical prediction of hydrodynamic noise, different computational methods of flow induced noise are summarized.A comparison is finally made among three methods in particular, all of which are potential schemes that can be applied in predicting vehicle's hydrodynamic noise.
